Getting Buena's Number
If you manage to save up 30p without spending any, Buena will give you her phone number. With this number she will call you from time to time offering gossip and advice on things in the Pokemon world. Once you save up 30p you'll have to spend some before you can collect more so make sure you get Buena's number before you do.
